A few weeks ago I could read a djvu book in Calibre by clicking on "VIEW." Now, when I try it, Calibre brings up an ePub reader and an apparent attempt at conversion ensues. To stop the conversion before my laptop heats up I have to go to Processes (Windows 7) and delete the offending process (identified as a Calibre process.)
I can read a djvu book outside of Calibre. using WinDJViewer. I have the appropriate file association for it, and can double click on the file name in Windows Explorer.
I'll bet there's some setting that will allow me to read the book when it's cataloged in Calibre. Can someone help?
